Hi, Friends, I tried to display a text using I2C few times using various method. But I can not succeed. Black boxes are displayed instead of text. I adjusted contrast, Address etc and checked all connections. But my LCD panel and Arduino are working. Please help. I used HD44780 library but nothin…

HD44780 library reports one I2C device but no working LCD
